Schaeffer Sondey offered to send along the list of Warner motor Service Letters and AD Note Index. This includes 18+ service letters in PDF format. I added a link at “Resources for Monocoupe Restorers“, which will take you to a new page with the complete list and links to the indivdual service letters. Clicing on a service letter will load a new page with that service letter. Here is a direct link to the service letter page. Thanks Schaeffer!
